You are monitoring the decay of 13-cis-retinal to all-trans-retinal. Initially, your sample contains 100% 13-cis-retinal. After 5 minutes, you see that 55% of your sample has converted to all-trans-retinal. Assume that the all-trans-retinal cannot convert back to 13-cis-retinal.
a. What is the rate constant that describes the transformation of 13-cis-retinal to all-transretinal?
b. How long will it take for 95% of the sample to be converted to all-trans-retinal?

Suppose a radioactive sample initially contains N0 unstable nuclei. These nuclei will decay into stable nuclei,...
Suppose a radioactive sample initially contains N0 unstable nuclei. These nuclei will decay into stable nuclei, and as they do, the number of unstable nuclei that remain, N(t), will decrease with time. Although there is no way for us to predict exactly when any one nucleus will decay, we can write down an expression for the total number of unstable nuclei that remain after a time t: N(t)=N0e−λt, where λ is known as the decay constant. Note that at t=0,...

The Aldol Condensation Precautions: Acetone, ethanol and acetophenone are flammable; work in a fume hood. Sodium hydroxide is a strong base and can cause severe skin burns and eye damage. Safety goggles are required. Gloves are recommended. Purpose To carry out two Aldol condensation reactions in which no heat is needed to obtain the condensation product.

Background (Part 1): We are continuously exposed to ionizing radiation from natural and artificial sources. All of us are exposed to radiation every day, from natural sources such as minerals in the ground and cosmic radiation to man-made sources such as medical x-rays. According to the National Council on Radiation Protection and Measurements (NCRP), the average annual radiation dose per person in the U.S. is 620 millirem. In this activity, you will use the interactive online dose calculator to estimate...

It will then repeatedly request the price for an item to be purchased or to quit. If given a price, it will accept nickels, dimes, quarters, one-dollar and five-dollar bills—deposited one at a time—in payment. When the user has deposited enough to cover the cost of the item, the program will calculate the coins to...
